Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Use) The present invention relates to a siphon coffee extractor including a storage container heated by a heater and an extraction container arranged on the storage container. .

(Prior Art) A conventional siphon coffee extractor will be described with reference to FIG. 1 is a support having a handle portion 2,
The holder 3 is provided on the support 1. Further, 4 is a storage container, 5 is an extraction container having a water passage pipe 6 and a filter 7. Coffee powder is put in the extraction container 5, while water in an amount corresponding to the amount of coffee powder is put in the storage container 4. The storage container 4 is held by the holder 3, and then the extraction container 5 is joined to the storage container 4 and held in the same manner, and the extraction container 5 communicates with the storage container 4 through the water pipe 6 and the filter 7. . In this state, the heater 8 is placed below the storage container 4 to generate heat to heat the water in the storage container 4. Eventually, the water in the storage container 4 boils and generates steam to increase the steam pressure, so that when the steam pressure reaches a certain pressure or higher, the hot water in the storage container 4 is extracted through the water pipe 6 and the filter 7. It is raised into the container 5 and mixed with the coffee powder to extract the coffee liquid. After this,
After the heater 8 is turned off to stop the heating, the heater 8 is moved away from the lower portion of the storage container 4
The storage container 4 is quickly cooled without applying the residual heat of the storage container 4 to the storage container 4. Then, since the vapor pressure inside the storage container 4 drops, the coffee liquid in the extraction container 5 is stored in the storage container 4 through the filter 7 and the water pipe 6.

(Problems to be solved by the invention) However, in the conventional siphon-type coffee extractor, after the extraction of the coffee liquid is completed, the vapor pressure inside the storage container 4 is quickly lowered to transfer the coffee liquid to the storage container 4. In order to lower the heater, it is necessary to move the heater 8 from below the storage container 4, and it is difficult to automate the coffee liquid extraction in the siphon coffee extractor. Further, in order to facilitate this automation, a structure in which the lower portion of the storage container 4 is cooled by a method in which the heater is not moved has been considered, but this has a poor cooling effect, so that the vapor pressure inside the storage container 4 can be quickly changed. There is a problem that the coffee liquid cannot be lowered to the extraction container 5 by lowering it.

An object of the present invention is to provide a siphon-type coffee extractor that can quickly complete extraction of coffee liquid without moving a heater.

[Structure of the Invention] (Means for Solving Problems) The present invention provides a storage container heated by a heater to achieve the above object, and communicates with the inside of the storage container via a water pipe. As described above, the extraction container is provided, and the cooling fan that cools the upper portion of the storage container after extracting the coffee liquid is provided.

(Operation) When the hot water in the storage container boils and rises into the extraction container and the coffee liquid is extracted, the heater is turned off and the cooling fan rotates to cool the upper part of the storage container. Even without moving the heater, the coffee liquid quickly descends from the extraction container and is stored in the storage container.

A packing 30 is provided at a connection portion with the water passage pipe 29 which is the neck portion of the extraction container 27, and while inserting the water passage pipe 29 into the storage container 26, the packing 30 is pressed into the mouth portion of the storage container 26. By doing so, the extraction container 27 is provided on the storage container 26, and at the same time, the extraction container 27 is provided via the storage container 26.
It is held at 4. Reference numeral 31 is a louver provided on the side of the cooling fan 17, and the louver is provided with the cooling air generated by the cooling fan 17 and the storage container 2
It is adjusted to the top of 6.

Next, the operation of the above configuration will be described. First, a predetermined amount of coffee beans is stored in the mill case 18 and an appropriate amount of water is stored in the storage container 26. Motor 1 in this state
By rotating 3, the cutter 15 rotates and crushes the coffee beans. The ground coffee powder passes through the mill filter 19, is guided by the coffee powder guide 20, and is stored in the extraction container 27. After this, the heater 12
Is energized to heat the water in the storage container 26. When the water in the storage container 26 boils due to this heating, the pressure in the storage container 26 rises, so the hot water rises through the water pipe 29 and flows into the extraction container 27 via the filter 28.
Then, the coffee powder and hot water in the extraction container 27 are mixed to extract the coffee liquid. On the other hand, when hot water flows into the extraction container 27, the heater 12 is cut off and at the same time the cooling fan 1
7 rotates, the cooling air generated by this is changed in direction by the louver 31, and is blown to the upper part of the storage container 26 to cool the storage container 26. Then, the pressure in the storage container 26 decreases, so that the coffee liquid extracted in the extraction container 27 is stored in the storage container 26 through the filter 28 and the water pipe 29.
